Question

Which should be the first step in solving the equation 1.2 w -3.8= 12.4

Answer 1

Add 3.8 to both sides of the equation

Answer 2

Answer:

Option 1 - Add 3.8 to both sides of the equation.            

Step-by-step explanation:

Given : Equation  $1.2w-3.8=12.4$

To find : Which should be the first step in solving the equation?

Solution :

Equation  $1.2w-3.8=12.4$

Step 1 - Adding 3.8 both side,

$1.2w-3.8+3.8=12.4+3.8$

$1.2w= 16.2$

Step 2 - Divide 1.2 both side,

$\frac{1.2w}{1.2}=\frac{16.2}{1.2}$

$w=13.5$

Therefore, The first step in solving the equation is 'Add 3.8 to both sides of the equation.'

So, Option 1 is correct.
